Hi guys,I'm just starting to come away from double
Di set up, to use the 40"membrane plus x2 20" filters to get my water.Any recommendation where to get the best value for money/price for these items.Thanks in advance

Was Pure Freedom but it’s now window cleaning warehouse as they’ve bought them out,I have the boosted 40” with 2x 20” pre filters makes water quick 1000ltrs in 2-3 hours.
The booster pump gives me pressure of anything between 115-140psi.

My water pressure is only 60psi.Would you recommend getting a booster?

Or buy an HF5 membrane.

Does the HF5 membrane allow you to produce water quicker even with the 60psi tap pressure?
It does say on Xline website that 60psi tap pressure is ok but it takes for ever to fill my 1,000 litre holding tank.
If the water goes through the filter and membrane faster will they last longer?
I'm used to x2 DI vessels and to make the resin last longer the water from my tap went through slowly to make the resin last longer.

My HF5 membrane produced around 2lpm of pure with 50psi when new. It's now over 10 years old and still producing at a rejection rate of 97%, but it's a little slower. It took around 10 hours to refill about 800 litres of pure in my IBC tank last week. But our incoming water is still cold. That's fine for me, as my IBC tank is controlled by a float switch and solenoid valve. It will automatically switch the water to the r/o off when the tank is full, even if it's 3am in the morning. I change my 20" Fiberdyne carbon filter every 77,000 litres of pure and waste combined.

See previous comment above.

Slowing the water flow down will help the carbon block filter to be more efficient. Fiberdyne do use a figure of 7.6Lpm on their 20" carbon block filter. Logic would tell be that at a higher water pressure, the membrane materials would wear quicker. But I don't know for sure.

The same applies to carbon filters. I doubt that a higher water flow would affect the sediment filter.
